I would like to know if anything on the LM4 is proprietary? Specifically the handguards, pistol grip, stock, and the trigger guard. Before I start buying parts I wanna know about compatibility. Is the Delta Ring a real steel type? Is the buffer tube Milspec or commercial? Can you remove the front sight? I want all real steel Magpul USA because I frown on PTS quality. I just wanna make sure everything is compatible.

Buffer tube is milspec. Im with you on the Magpul USA over PTS stuff though. I haven't really experienced any issues with their products YET, though have you? This is one of the reasons why I bought a real steel MVG for my soon to be LM4, Il put it in my sig like yours so you can see.
Also, what type of front MBUS mount do you have on it?

Interests:Keeping those damn squirrels from putting their filthy little paws on my peaches in my backyard. Oh, Yes. It's not just a hobby, its a passion!!

More information may be released as we near the official launch. I know we are all excited for the LM4 and I totally understand but let's wait a bit longer and actually get the new gun first in our hands before we start with modifications.

I highly suggest that you all hold off with conjecture regarding what will and won't work, what is and is not Mil Spec. Until the gun is actually released, things can change. The Mods will have the information you need at or very shortly after the actual release.
